With the latest iPhone OS 3.1 update, iPhones start identifying themselves correctly, and if the ActiveSync policy configured by the administrator requires device encryption (see Figure 1 below), data on the device is encrypted. That's great news— unless you happen to have an older iPhone. If you're using the (Original/Classic/2G/1G?) iPhone , or the iPhone 3G, and device encryption is required, you will be unable to log on to your mailbox.

Important to remember these days, when execs start sporting iPhones.
